- A coast � also called the coastline, shoreline, or seashore � is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. Coasts are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves. The geological composition of rock and soil dictates the type of shore that is created. Earth contains roughly 620,000 km (390,000 mi) of coastline.

Sagitta, the third-smallest constellation in the sky, has no stars brighter than fourth magnitude, but it was well-known to the Greeks and was among the 48 constellations listed by Ptolemy in the Almagest. Aratus described it as ‘alone, without a bow’ since there is no sign of the archer who might have shot it.
